Garmins next-generation, 4 kW high-definition GMR 18 xHD dome radar pairs ease of use with advanced open-array features. Its intuitive operation makes modes and settings simple to understand so you can enjoy great performance without a lot of technical know-how.
The GMR 18 xHD delivers higher resolution than our previous generation 18" dome radars. New Dynamic Auto Gain and Dynamic Sea Filter continually adjust to your surroundings, providing optimal performance in varying conditions. Choose from multiple levels of aggressiveness or use manual gain adjustment. Dual range operation allows fully independent split-screen display of far and close radar views in full 8-bit color (select chartplotters); range of 48 nm. ?No Transmit Zone" protects areas behind the radar from being radiated while providing full forward-looking radar capability.
